I knew that, or we knew that.. it's a T-Mobile MVNO. They really have no access to "unlimited" resources. I tried to tell someone else that but they didn't quite understand that. 1000MB is more than enough for most.
What we're the ones doing on their phones to use up that much data? With light browsing, constant Twitter updates in the background, 3 email accounts updating every few hours, MOTOBLUR (FB+Twitter+Myspace) Google Maps, occasional Slacker tuning/Skyfire Flash content/tethering and various network speedtests I still have a hard time getting over 1GB/1024MB and this was before I let my phone sleep on WiFi.
